Application filed March 31, 1893. Serial No. 468,519 (No model- To aZZ whom it mz'yconoern:

Be it known that I, FRANCES V. STEWART, of Atlanta, in the county of Fulton and State of Georgia, administratrix of GEORGE W. STEWART, deceased, who did in his life-time invent a new and Improved Marine Signal, do declare the following to be a full, clear, and exact specification of the same.

The invention relates to apparatus adapted to signal. from one vessel to another, the water being utilized to conduct the sound, and the object of the invention is to provide an improved and efficient apparatus of this character adapted both to transmit and receive sigjnals, as hereinafter described.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the views. t

Figure 1 is a partly sectional side elevation of an apparatus embodying the invention, applied to the bow of a vessel. Fig. 2 is a sec- Lional. pla ice, on line 22 in Fig. 1; and Fig. 3 is a vertical sectional viewillnstrat-ing a modification.

In constructing an apparatus embodying the preferred form of the invention, a head A. is provided, having a chamber a, to which an inlet 0. leads, and at such inlet a pipe B is connected. to the head A, for conveying steam or compressed -air to the chamber a. The upper end of the pipe B, is fitted in the tube 0, in which it is adapted to telescope, said tube being closed at its upper end. To

tube 0, near the top,'a pipe D is connoctcd, which pipe leads to a reservoir, boiler or the like, ll, located in the vessel and adapted to contain compressed air or to generate steam for supplying the chamber a. A suitable valve ol provided in the pipe D, andcontrollcd as by an operating rod l-D', from made by a corresponding signal apparatus located on another vessel at a distance, and at the top orside such bell inouthis provided with an outlet r adapted to receive a pipe or tube I, which extends to near the top f the tube 0, where a, flexible pipe I, is connected thereto and extends to the pilot house h", or other part of the vessel, thereby conducting l the sound received by the bell mouth G.

'lheapparatus is preferably arranged at the bow of-the vessel, as shown, and for this purposothe tube 0 is cast or formed With a flange or laterally-projecting plate U, adapted to be bolted to the deck as shown, and at' thelower endof the tube 0,21 lugf', is formed, to whichis secured 3. depending rod or spindie J, which is formed with a laterally-projecting fork, or diverging armsj, adapted o embracegand be bolted to the vessel at each side of ihe bow, below the waterline. A

portion of the steamer air pipe B is made flexible, as: at h." To the head A, chains K are secured, and carried up over idlers L, to .a Windlass M on the deck- With this c0nsl'ruction, ibwill be seen that the signal may be raised on the spindle J, the pipe 13 telescoping in the tube 0, and may be quickly lowered in any and all positions and depths I below the water line and even. with the surface of the water when it is desired to signal or receive signals. Further the flexible p91-- tion of the pipe B,'permits of the signal be- .ingswung around to describe an arc, with the spindle -J as a center, for bringing the apparatus into line with any vessel within its range.

When not required for use, the apparatus may be drawn up out of the water, as will readily be understood. The,edge of the bell mouth G, may be slotted to provideresonab ing fingers or projections 1 if desired.

in Fig. 3 is shown a slight modification, in which the bell inrmeh G, theoutlct gQand the steam pipe 13 are, or may .be of the same form as shown in the other figures; but instead of a steam whistle, the signal device is in the form of a reed. ii, fitted in a coupling section B Atthe bottom of the reed a check valve N is provided for preventing entrance of Water to the ohmnbcr or pipe containing the reed.

It will be evident to the skilled mechanic that the details of the device may be varied. ihe essential features of the invention are defined in the claims hereinafter made. Also any suitable means may be provided for retaining the apparatus in the laterally adjusted position;

Having thus described the invention, what is claimed as new, and desired-to be secured oy Letters Patent, is-- 1. In marine signal apparatus, the combination, with a signal device provided with connections to establish comm unicaticn with a source of steam or air supply, of a sound receiver carried by the signal device and having an outlet to receive connections for conducting sound from the receiver to the desired point on a vessel, substantially as der scribed.

2. In marine signal apparatus, a head provided with a signal device and operated by steam or compressed air, and a bell mouth on said head having an outlet to receive a pipe for conducting the sound received by such bell mouth, substantially as described.

3. In a signaling apparatus, the combination of a sliding and swinging signal head having a bell mouth, and a steam or eoanpressed airoperated signal device carried by the said head, substantially as described.

4. In a signaling apparatus-the combine,

tion with guide rod, of a hes-d having-a hell I 5. In signaling; apparatus, the combine:

tion, with a head having a signal operating by steam crair, of connections for supplying the latter, said connections including a tube adapted robe secured to a deck or the like, and the signal pipe telescoping in such tube, substantially as described.

6. The combination, with a vessei,of asignaling apparatus secured thereto at the bow, and comprising the following: elements: a head having a signal device operating by steam or air, a spindle on which such head is vertically adjustable and pi-vcted for lateral movement, a pipe leading to such head for conveying steam or air thereto, a bell mouth on the head, forming a scund receiver, an outlet and a sound conducting pipe leading from the hell mouth, and means for raising and lowering the head and its appurtenances, substantially as described.
